There is an artificial line that splits the island of Hispaniola in two. On one side is Haiti, and on the other is the Dominican Republic.
There was a time when that split between the two countries was drawn with blood; the 1937 Parsley Massacre is widely regarded as a turning point in Haitian-Dominican relations. The slaughter, carried out by Dominican dictator Rafael Trujillo, targeted Haitians along with Dominicans who looked dark enough to be Haitian -- or whose inability to roll the "r" in perejil, the Spanish word for parsley, gave them away.
The Dajabón River, which serves as the northernmost part of the international border between the two countries, had "risen to new heights on blood alone," wrote Haitian American author Edwidge Danticat.
"The massacre cemented Haitians into a long-term subversive outsider incompatible with what it means to be Dominicans," according to Border of Lights, an organization that commemorated the 75th anniversary of the massacre in 2012.
Today, things are as tense on the island as they have been in years. Within days, the Dominican government is expected to round up Haitians — or, really, anyone black enough to be Haitian — and ship them to the border, where they will likely be expelled.
The government has described it, in terms chillingly reminiscent of the Holocaust, as a "cleansing" of the country's immigration rolls.
